Abstract

A lateral pipe connection assembly that restricts to a minimal amount the penetration of a hub component of the assembly into the cored hole of the mainline pipe to which the assembly is connected. The assembly includes an elastomeric sleeve that is also configured to provide enhanced fluid sealing of the connection.

Claims (20)

1. A pipe connection assembly, comprising:
a cylindrical hub having an interior diameter and a leading end having an exterior beveled surface;
a cylindrical elastomeric sleeve having an inner end that includes a radially inwardly projecting lip that has a seat surface inclined to correspond to the beveled surface of the hub so that the seat surface engages the beveled surface of the hub when the leading end of the hub is inserted into the sleeve.
2. The assembly of claim 1 wherein the beveled surface of the hub defines a leading edge of the hub and wherein the lip includes an annular stop projecting inwardly to define a stop surface that is oblique to the seat surface and that obstructs penetration of the leading edge of the hub beyond the stop surface when the hub is inserted into the sleeve.
3. The assembly of claim 2, wherein the lip is shaped to define a pocket in the stop surface to receive the leading edge of the hub.
4. The assembly of claim 1 wherein at least a portion of the seat surface normally extends from the sleeve by an amount sufficient to compress that portion as the seat surface engages the beveled surface of the hub when the hub is inserted into the sleeve.
5. The assembly of claim 4 wherein the sleeve fits into a hole in a pipe that has an interior surface, the sleeve further comprising a radially outwardly extending rib formed thereon and arranged to abut the interior surface of the pipe when the sleeve is fit into the hole, thereby to restrict rotation lip out of the path of the hub as the hub is inserted into the sleeve and thereby facilitate the compression of the portion of the seat surface.
6. The assembly of claim 4 wherein the protruding portion of the seat surface is a semi O-ring.
7. The assembly of claim I wherein the sleeve fits into a hole in a pipe that has a thickness and an exterior surface, the sleeve further comprising a radially outwardly extending rib formed thereon and arranged to abut the exterior surface of the pipe when the sleeve is fit into the hole, and wherein the lip is spaced from the rib by an amount less than or substantially equal to the pipe thickness thereby to cause the seat surface to be compressed between the beveled surface and the pipe when the leading end of the hub is inserted into the sleeve.
8. The assembly of claim 7 wherein the beveled surface of the hub defines a leading edge of the hub and wherein the lip includes an annular stop projecting inwardly to define a stop surface that is oblique to the seat surface and that obstructs penetration of the leading edge of the hub beyond the stop surface when the leading end of the hub is inserted into the sleeve.
9. The assembly of claim 8, wherein the lip is shaped to define a pocket in the stop surface to receive the leading edge of the hub.
10. The assembly of claim 1 further comprising annular protrusions formed on an inside surface of the sleeve to be compressed between the sleeve and the hub when the hub is inserted into the sleeve.
11. The assembly of claim 10 wherein the annular protrusions are located to be compressed between the sleeve and a part of the hub that is spaced away from the beveled surface.
12. The assembly of claim 10 wherein the sleeve fits into a hole in a pipe and further comprising annular protrusions formed on an exterior surface of the sleeve to be compressed between the sleeve and a pipe into which the sleeve is fit when the leading end of the hub is inserted into the sleeve.
13. A method of making a cylindrical elastomeric sleeve that fits into a hole in a main pipe that has in interior surface and into which sleeve a rigid cylindrical hub may be inserted in order to facilitate connection of a lateral pipe to the main pipe, the method including the steps of:
forming the sleeve to include a radially outwardly extending rib;

forming the sleeve to include a radially inwardly projecting lip that has an inclined seat surface as well as a radially inwardly projecting stop that projects inwardly and defines a stop surface that is oblique to the seat surface; and shaping the sleeve so that the lip projects radially inwardly, and the radially outwardly extending rib abuts the interior surface of the main pipe so that the when the sleeve is fit within the hole without a hub being inserted into the sleeve the lip is restricted from rotating out of the path of a leading end of a hub that is inserted into the sleeve.
14. The method of claim 13 including the step of forming at least a portion of the seat surface to extend from the sleeve by an amount sufficient to compress that portion as the seat surface engages a hub when the hub is inserted into the sleeve.
15. The method of claim 13 wherein the sleeve is usable with a hub that has a beveled leading end and including the step of shaping the incline of the seat surface to correspond to the bevel in the hub leading end.
16. The method of claim 13 including the step of forming annular protrusions on an inside surface of the sleeve to be compressed between the sleeve and a hub when the hub is inserted into the sleeve.
17. The method of claim 13 including the step of forming compressible annular protrusions on an exterior surface of the sleeve.
18. A method of making a cylindrical elastomeric sleeve that fits into a hole in a main pipe that has a thickness and an exterior surface, and into which sleeve the leading end of a rigid cylindrical hub may be inserted, the method comprising the steps of:
forming the sleeve to have a radially outwardly extending rib thereon and arranged to abut the exterior surface of the main pipe when the sleeve is fit into the hole;
forming the sleeve to include a radially inwardly projecting lip that has an inclined seat surface as well as a radially inwardly projecting stop that projects inwardly to define a stop surface that is oblique to the seat surface; and sizing the sleeve so that the lip is spaced from the rib by an amount less than or substantially equal to the pipe thickness, thereby to cause the seat surface to be compressed between the leading end of a hub and the pipe when the hub is inserted into the sleeve.
19. The method of claim 18 including the step of forming annular protrusions on an inside surface of the sleeve to be compressed between the sleeve and a hub when the hub is inserted into the sleeve.
20. The method of claim 18 including the step of forming compressible annular protrusions on an exterior surface of the sleeve.
